Thinking about the graph of y, the rate of change is zero whenever there is an extremum.
First, differentiate y.
Next, find the zeros of y' by factoring.
Now, we substitute these x-values into the
original equation to find the coordinates.
Answer:
x = 9
Step-by-step explanation:
y = 2/3x - 6
If the y point is 0, then plug that number into the equation and solve for x.
0 = 2/3x - 6
Add 6 to both sides of the equation.
6 + 0 = 2/3x - 6 + 6 or 6 = 2/3x
Multiply both sides by 3.
3 x 6 = 2/3x x 3 or 18 = 2x
Divide both sides by 2
18/2 = 2x / 2 or 9 = x
The equation would be .05x+50=100 Then you would solve for x

Let's look at the first row:
cost = _______ + _______ * (monthly payment)
The first blank should be the "down payment" because this is the initial, constant value that is paid. The second blank should be the "number of months" because this way, when multiplied by the actual amount each payment is (monthly payment), then we get the total amount paid during those months.
So, we have:
cost = (down payment) + (number of months) * (monthly payment)
Now for the second row, we just plug in numbers and variables:
335 = 50 + 6 * p
Finally, we can solve for p:
335 = 50 + 6p
6p = 285
p = $47.50
